Alcohol adds just a few things to your race prep and helps a few. Where I get my 54 gallon barrel of alcohol it comes with upper end lube already added for 165 dollars a drum. I rebuild my carb before each race season giving it a good cleaning and flush. I change out my floats every two years. I never start my engine like some guys do and rev it up to empress my friends. COLD starts make WATER. On race day I unload and when they call the class before me I drive around getting it up to at least 180 degrees using my lean out valve. My lean out valve is a simple 1/2 inch ball-valve plumbed into either my carb, carb spacer, or back of my intake manifold. Open it up, lean it out and build heat. After a pass I pick up my time slip, shut off my electric water pump, fan, and build heat driving back to my pit spot. I never have to run my pump or fan in the pits to cool the engine. This heat helps burn off any moisture that would come from running cool. I found Brad Penn oil (now Penn Grade) is a great oil for alcohol. Racing almost every weekend like I do I could probably get away with two oil changes a season but usually do it 3 times so I can check the oil filter. With alcohol HEAT is your friend not your enemy. Rich jetting POLLUTES the oil so an EGT readout really helps getting your jetting right.
